What to Watch Wednesday

Jason Segel stars as David Foster Wallace in “The End of the Tour,” about that author’s book tour for “Infinite Jest.” And cable TV provides opportunities to see both “The Avengers” and its bombastic sequel, “Avengers: Age of Ultron.”

What’s Streaming

THE END OF THE TOUR (2015) on Amazon and iTunes. In the mid-1990s, soon after David Foster Wallace’s magnum opus, “Infinite Jest,” was published, the journalist David Lipsky (Jesse Eisenberg) pitched a profile of the author to Rolling Stone. His editor sent him to accompany Wallace (Jason Segel) for the last stop on the book’s tour, but the article never ran. After Wallace’s suicide in 2008, Mr. Lipsky wrote a memoir about the trip, which inspired this film. But, A. O. Scott wrote in The New York Times, Wallace is hardly the main subject. The movie, he said, “is at once an exercise in post-postmodern literary mythmaking and an unsparing demolition of the contemporary mythology of the writer. It’s ultimately a movie — one of the most rigorous and thoughtful I’ve seen — about the ethical and existential traps our fame-crazed culture sets for the talented and the mediocre alike.” (Image: Mr. Segel)

What’s on TV

AVENGERS: AGE OF ULTRON (2015) 6:35 p.m. on Starz. The summer blockbuster gang is back to defend the world against the latest doomsday-obsessed villain in Joss Whedon’s follow-up to his wildly profitable “Avengers” film in 2012. More than 15 A-list celebrities make up the ensemble cast, rounded out by the newcomer James Spader as the robotic nightmare Ultron. Opinions, Manohla Dargis wrote in The Times, are more or less irrelevant with this type of film. “It was created to crush the box office, entertainment media and audience resistance, and mission, you know, already accomplished,” she added. If you feel behind and need to instead catch up with “The Avengers,” it is on FX at 7 p.m. “The best scenes,” A. O. Scott wrote in The Times, “are not the overblown, skull-assaulting action sequences — which add remarkably little that will be fresh or surprising to devotees of the ‘Transformers’ franchise — but the moments in between, when the assembled heroes have the opportunity to brag, banter, flirt and bicker.”(Image: Ultron)

BROAD CITY10 p.m. on Comedy Central. Ilana accompanies Abbi to the Philadelphia suburbs to visit her father (Tony Danza) and find what nostalgic treasures await in Abbi’s childhood bedroom. Ilana comes across a valuable commemorative Beanie Baby, and Abbi finds money she raised — but never delivered — for a hospitalized classmate during high school. They set out to find her, and reliable hilarity ensues. (Image: From left, Mr. Danza, Abbi Jacobson and Ilana Glazer)

YOUNGER10 p.m. on TV Land. Liza wonders whether it’s time to say goodbye to her 26-year-old life after tragedy strikes.
